5.2.1 Minimum distance
For access protection, a minimum distance (S) must be maintained between protective
field and hazardous area. This safety distance ensures that the hazardous point can only
be reached after the dangerous state of the machine has been completely stopped.
The minimum distance S as defined in EN ISO 13855 and EN ISO 13857 depends on:
reach or approach speed
stopping/run-down time of the machine or system
(the stopping/run-down time is shown in the machine documentation or must be
determined by taking a measurement. — On request SICK service can perform a
stoptime measurement on your system.)
response time of the S3000
supplement C against reaching through
How to calculate the minimum distance S (see EN ISO 13855):
First, calculate S using the following formula:
S=(K × (T
M
+ T
S
)) + C
Where …
K = Approach speed (1600 mm/s, defined in EN ISO 13855)
T
M
= Stopping/run-down time of the machine or system
T
S
= Response time of the S3000
C = Supplement against reaching through (850 mm)
